JAMES o. HAYns, or BRooKFiE n 'IssouRL Hose-construe.

1 b all whom it may concern:

Be it known that Llamas, t HAYES, a citizen of the United States, residing at Brookfield, in the county of Linn and State of Missouri, have invented certain new and useful Improvements in Hose-Couplings, of. which the following is a specification.

My invention relates to improvements in hose couplings, the obje t ofthe invention being to provide a hose coupling which may be quickly-coupled and uncoupled, which will be steam tight when themembers are together, and which may be readily taken apart and-repaired when desired. v

A further object is to provide a hosecoupling with an improved arrangement of'cougasket, by means of which the gasket may replaced when desired.

With these and other objects in'view, .th

invention consists in certain novel features rangements of parts as .will be more fullyi hereinafter described and pointed out in the In the accompanying drawingsz-Figure 1 is a view in side elevation illustrating my improved hose coupling. Fig. 2 is a View in side elevation of one member of the hose coupling.- Fig. 3 is a top plan view of the construction 'shown in Fig. 1. Fig. 4: is a view in longitudinal section of one of the coupling members Fig. 5 is an endyiew of one of the coupling members. Fig. 6 is a view in section on the line 6,6 of Fig. 4 illustrating the draw nut only. is aview in side elevation of a gasket. F S is a view in elevation of a slightly modified form of tube.

My improved coupling comprises two members l and 2 which are precisely alike in construction, yet reversely positioned. so that they effectually couple when together. The description of one member will apply alike to both.

Each coupling member comprises a coupling head 3, a draw nut 4, a coupling tube 5, and a gasket 6,'constructed and a sembled as will now beeXplained. The head 3 is circular in cross section and cvliiulrical throughout the greater portion of its length,

and at one side is provided with an exten- Specification of Letters Patent, App 1. ltidIrfilBdApIfl 9, 1913. Serial No. 759,887.

to interlock with a dove-tailed lug 10.0n the fiat surface 8, so that when the two members are placed together with the'ex'tensions of the members besidethe fiat faces of the members and moved laterally, the locking flanges 9 constitute cams in engagement with the lugs 10 to move the members longitudinally toward each other," and draw their meeting. ends together.

Integral lugs l'l o n each member, when the two members are drawn together, are projected intoprecesses' 12' in'the other member to prevent the members falling apart when once coupled together. In imparting the necessary movement to the members to cause them to interlock, theyare positioned .angularly with-relation'to eachother, and

then-forced into alinement, the lugs 1l=act ing to hold the parts -against lateral movementduring this operation.

The -head 3 of each couplingmember, at

its rear end,,is-reduced in diameter and formed with an annular flange 13 which has swiveled connection with the draw nut 4 above referred to. The draw nut 4: 1s ma'dehexag'onal at one endas shown at 15' for the-reception of a wrench to turn the same, and at ts other end is cylindrical and recessed in one .side as shown at 16 to allow the flange l3 a ready entrance into the nut.

The metal tube 5' above referred to is of two external diameters, the larger external diameter screw-threaded and engaging internal threads in the draw nut 4. The smaller diameter of the tube jo-fits snugly within the bore 17 of the head 3, and at its extreme end is externallyscrew-threaded engaging internal threads in the gasket 6. T liisgasket- 6 is located within a recessed seat 19 in the outer end of the coupling head and is provided with an opening -20 to aline with an opening 21 in the head and receive a pin (not shown) to hold the gasketagainst. rotary movement and allow the tube 5 to be unscrewed therefrom so to permit the removal of the gasket and a new one to be substituted therefor.

The arrangement of the draw nut 4, tube 5 and head 3, it will be observed, by the t-urning of the draw nut. operates to move the head 3 longitudinally on tube 5, and as shoves-ct forth. this tube 5 is of two external diameters so that a shoulder 32 is formed at the juncture of the two diau'ieters which shoulder bears against the end of head 3 and binds the parts securely together.

, In Fig. 4 I show a hose connection 23 screwed onto the end of tube 5, but instead 5 of employin I employ ajtu e 24 illustrated in Fig. 8 in which form thelarger diameter of the tube is provided with an annular groove .25, so

readily clamped to'this tube.

- The free end of each extension on'its up- 'per edge is formed with a lug or raised p012 t-i'on 26, and various slight changes might -',bei.'m a'dein thegeneral form andarran'ge ent' 'of partsdescribed without departing myself to the precisedetails set forth,but' co'ns'i'der myself at liberty to make such.

changes and alterations as fairly fall within fth'e'spirit'and scope. of the appended claims.

,. Having thus described my invention, what; I claim as' new and desire to secure by Let ters Patent is: p

1. A hose coupling, comprising two members, said members havinginterlocking engagement :with each other, each member comprising a head, 'a'draw nut, and a coupling tube externally screw-threaded 'at both ends, the threads at one end engaging the threads of Y the nut, and said nut having swiveled connection with the head, said head atits outer end having a gasket seat therein,

an internally screw-threaded gasket located within the seat and engaging the screwthreads on the other end of the tube, and

said gasket and head having registering openings, substantially as described.

2. A hose coupling comprising two memthis form of tube 5, I might' that. any ordinary form of hose .may be stantially as described. A

om my invention, and hence I-donot limit 'mgs; a nut threaded on the other end of said tube and swiveled tosaid head, sub- 3. A hose coupling comprising two members each having interlocking engagement A EYVlbh the, other, each member comprising a coupling'tube threaded at both ends and a shoulder intermediate, its length; ahead slidably mounted on said tube, rovided with an annular rib on one end an having .anannular recess in its other end a gasket in said annular recess and threaded on one of the threaded ends of said tube, said gasket and head having registering 0pen-" ings; afnut threaded 'on the other end of said tube, said nut being providedwith an internal annular, groove in engagement with the annular rib on said head; and a recess in one side permitting the engagement and disengagement of said rib and groove,-substantially as described. In testimony whereofl have signed my name to this specification in the presence of two subscribing: witnesses.-
